4th Qtr. Digestive System
This system has a major role in our body where it breakdowns food which enters thru our mouth and gives us vitamins and minerals to help maintain our body's strength and energy to move efficiently. In the outskirts of this process, the digestive system is considered a system which is an important aspect in our lives

4th Quarter Blog: Lymphatic System
What I learned from the lymphatic system is that without this body system, our human state will easily be defected against certain foreign materials that will enter our body and later cause harm to them. Not only that, several of our body systems will be facing so many collateral damage that in the end, we will end up dead

4th Quarter Blog: Respiratory System
1. Lungs
2. Air sacs
3. Muscles
4. Upper and Lower Airways
5. Thoracic Cage
Each of these major parts help in contributing the process of breathing in our body. Without their supportive functions, we won't be able to sustain enough air we need for our body.

3rd Qtr. 1st week
What I learn from this body system is that its works together with the nervous system to regulate the activities of all the body system. It secretes hormones that act on cells by binding to external receptors, causing changes in enzyme activity inside the target cell. Hormone levels can be regulated by 3 mechanism:
- Neural Control
- Hormonal Control
- Humoral Control

Biology report 2nd semester part 3
- The Brain is a hierarchial organ that is divided into compartments, each with specific functions. It also has nerves attached to it, called cranial nerves. There are 12 pairs of cranial nerves and they can sensory, motor and mixed.
- The cerebrum controls the consciousness or movement & senses of a human body. Beneath it are the diencephalon, brain stem, and cerebellum. Each parts play an important role in coordinating the sensory and motor information of the cerebellum. Other parts of the brain allow humans to make connections between different types of sensory information and to compare current experience
The nervous system plays a significant role in providing our body to move and make contact with our surroundings. Without it, we won't be able to fuction properly.

Biology report 2nd semester part 3
is the body's computer
3 systems of the nervous system
Central nervous system:
controls all basic bodily functions and responds to external changes
Peripheral nervous system:
provides a complete network of motor and sensory fibers connecting the CNS to the rest of the body
Autonomic nervous system
parallels the spinal cord but is separated involved in control of exocrine glands, blood vessels, viscera and external genitalia
The nervous tissues are made up of two specialized cells:
1.Neuroglia or Glial cells
- cells in the nervous tissues that allow it to perform nervous system functions
2.Neurons
- all of the control functions of body are being transferred with the neurons.
- they work like messengers
Spinal Cord
- has 31 segments, each with a pair of spinal nerves
- ventral root is integral to motor functions and the dorsal root is integral to sensory functions

Biology report 2nd semester part 2
Definition:
is comprised of the skin and its accessory components of hairs, nails and associated glands.
Performs several vital functions besides protecting you from an invasion of disease-producing pathogens
helps keep the body from drying out, acts as storage for fatty tissue necessary for energy, and with the aid of some sunshine, your skin produces vitamin D.
Skin:
quite a large organ, easily weighing twice as your brain, approaching 20 pounds in an average adult
3 main layers:
epidermis:
- layer of skin that we normally skin.
- made up of 5 or 6 even smaller layers of stratified squamous epithelium
- the epidermis is interesting for several reasons:
- 1st, it has no blood vessels or nerve cells.
- 2nd, the cells on the surface are constantly shedding being replaced with new cells that arise from the deeper region called, “ Stratum basale.”
- the outermost surface of skin is actually a layer of dead cells called stratum cornerum
- specialized cells called melanocytes are located deep in the epidermis and are responisble for skin color. They produce melanin, which is the actual substance that affects skin color.
Dermis;
- another name: Corium
- made up of the following components in the layer:
capillaries
collagenous and elastic fibers
involuntary fibers
nerve endings
lymph vessels
hair follicles
sudoriderous glands
sebaceous glands
2 main types of sudiferous or sweat glands:
1. apocrine
- secrete at the hair follicles in the groin and region as well as the armpits.
2. eccrine
- found in greater numbers on your palms, feet, forehead, and upper lip
Subcutaneous Fasci ( Hypodermis)
- the innermost layer of the skin which is composed of elastic and fibrous connective tissue and fatty tissue.
Nails
- specialized epithelial cells originating from the nail root form your nails. As these cells grow out and over the nail bed, they become keratinized, foring a substance similar to the horns of a bull

Skin Burns
When assessing the damage caused by the burns, there are two factors:
The depth of the burn
size of the area damged
Types of Skin Burn ( in order)
1st degree burn - damages the outer layer of the skin only
2nd degree burn - burns the entire depth of the epidemis and a portion of the dermis
3rd degree burn - affects all of the 3 layers of the skin
4th degree burn - burns that penetrate to the bone

Biology report 2nd semester week 1
Functions:
- provides frame
- produces blood cells
- provides protection
- helps to breathe
- stores minerals
Types:
- Long Bones - larger than they are wide
- Short Bones - equal sized in width & length
- Flat Bones - thinner bones
- Irregular Bones - like parts of a jigsaw puzzle
- Compact - dense, hard. outer layers of the other bones
- Spongy - arranged in trabeculae
- not smooth
- have projections, bumps & depression
- Ossification - formation of bone
- Osteoprogenitor celss - non specialized cells found in the periosteum, endosteum, cnetral canal
- Osteoblasts - secretes a matrix of Ca
- Osteocytes - mature bone cells

Biology Project part 5
- the most abundant organic molecules in cells
- most genetic informationare expressed by proteins
- Enzymes are catalysts that speed the rate of chemical reactions. Its suffix is -ase
- Hormones are chemical messengers secreted by endocrine glands. They also regulate other parts of the body.
- Antibody is globular protein that is made by the body to response to presence of a foreign or harmful molecule called antigen
- Amino Acid are building blocks of proteins (monomers that make up the polymr protein)
3 types of Proteins:- Structural Proteins: important in maintaining the shape of the cells and organism.
- Regulatory Proteins: determine which activities will occur in the organisms
- Carrier Protein: pick and deliver molecules at one place and transport them to another place.

Biology Project part 4
- composed of carbon, hydrogen and oxygen atoms linked together to form monomers called mono saccharides ( simple sugar)
mono= single; saccharine= sugar
- means sweet carbon
- Formula= CH2O
- the ending -ose indicates carbohydrates
- triose means 3 carbons therefore C3H6O3
- serves as ab immediate source of energy
- provide shape to certain cells
- simple sugars combine to form complex carbohydrates
- Composed of 3 groups:
- Monosaccharides
examples: glucose, fructose, galactose
- Disaccharides
example: surcose, lactose, maltose
- Polysaccharides examples: cellulose, glycogen, starch
Learning carbohydrates can help teach us the what nutrients does it provide us everyday. Learning this topic for me has surprised me because of the fact that there certain properties in life that always help us in movement and giving information to our body.
- Monosaccharides
Biology Project part 3
- common, measurable indicators that help us to assess the health of patients.
- signs vital to life
- standard values can change according to sex and age
- Examples
- Pulse
- Blood pressure
- body Temperature
- Respiratory rate
- more subjective and more difficult to measure
- Example: pain
- A specific grouping of signs and symptoms is known as syndrome
- identification of disease determined by the study of the patient's signs, symptoms, history and results
- cause of disease
- prediction of the outcome of a disease

Biology Project part 2
- Epithelial Tissue is a tissue that not only covers and lines much of the body but also covers many of the parts found in the body. There different shapes for this tissue such as squamous (square/ flatlike), cuboidal (cubed-shaped), columnar (column shaped) and transitional (strechy and variably shaped). There are also two different arrangements. One is simple where the tissues are are arrange in a single layer. Another is stratified where the tissues are arranged in several layers.
- Connective tissues is a tissue that connects or separates other tissues or organs. There are 3 types of connective tissues which are Areolar where it holds the organs in holding other connective tissues, Adipose also known as fat where it is needed for proper functioning for our body and Dense Connective Tissue where the tissues form stonglike structures to wire cables.
- Muscle tissue is a band of fibrous tissues that has the ability to produce movement. There are 3 types of muscle tissues. One is Skeletal Muscle where it is connected to the skeleton to form part of the mechanical system that moves to the limbs and other parts of the system, another is Cardiac muscle where it is found in the walls of the heart and finally is the Smooth muscle where the tissue in within the contractile fibrulus aren't highly ordered, occurring in the gist and other internal organs
- Nervous Tissues are tissues that acts as a messenger. It has 2 parts that take part in sending information thru out the body. One is the Neurons where it is considered as th conductor of information and the other is Glia where it supports in holding the neurons inplace.

Biology Project part 1
What is cell division?
- Cell Division is the process of dividing one cell into two.
- Two Types:
- Mitosis, where eukaryotic cells separates the chromosomes in its nucleus into two identical sets in two daughter nuclei. The steps are:
- Interphase
- Prophase
- Metaphase
- Anaphase
- Telophase
- Meiosis is the division in which the number of chromosomes per cell is halved. The steps are:
- Meosis I
- ProphaseI
- Metaphase I
- Anaphase I
- Telephase I
- Meosis II
- Importance of the Study:
- For me, Cell Division is an important to learn for it allows us to know how things function well in our daily lives today. As we recall, without cell division, we won't be able provide special needs for our body.
