Answer:
A. Integumentary system
- body temperature regulation, cell fluid maintenance, synthesis of Vitamin D, and detection of stimuli.
Main Parts
1. Skin
Functions: chemical and mechanical barrier, biosynthesis, control of body temperature, sensory
Layers: Epidermis (Stratum Basale, Spinosum, Granulosum, Lucidum, Corneum) and dermis (papillary, reticular)
2. Hair
Types: vellus and terminal
Structure: Follicle and bulb (shaft, inner root sheath, outer root sheath, glassy membrane)
Nails
3. Nails
Nail plate, nail folds, nail matrix, nail bed, hyponychium
4. Secretory glands
Sweat glands: eccrine (most numerous, covering almost the entire body) and apocrine (only in the axilla and genitalia)
Sebaceous glands: Cover the entire body and secrete sebum (oily and fatty)
5. Subcutaneous tissue (hypodermis)
Adipose tissue that increases skin mobility, insulates the body, and acts as a shock absorber.
B. Digestive system
The digestive system breaks down food into nutrients such as carbohydrates, fats and proteins.
Main parts
Mouth for Chewing to break down food into smaller pieces.
Esophagus Peristalsis to move food to the stomach
Stomach to further digest food
Small intestine for final digestion and absorption of nutrients
large intestine to absorb water and minerals
C. Respiratory system
function of respiratory system is to breathe in oxygen for respiration and to breathe out carbon dioxide produced by respiration.
(The major organs of respiratory system in human beings are:
Nose
allows air to enter your body, then filters debris and warms and moistens the air. Your nose gives you a sense of smell
Trachea
carry air in and out of your lungs. it is a cartilagenous flexible tube, it provides a reliable pathway for oxygen to enter your body.
Bronchi
carry air into your lungs.
Lungs
External Respiration where exchanges Gases Between the Lungs and the Bloodstream.
diaphragm.
contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges and when you exhale it moves up to squeeze air out of the lungs.
D. Musculoskeletal system
for support, protection and movement
main parts
skeleton
for support and protection
muscles
for movement and it also gives shape to the body
tendon and ligament
Tendons connect your muscles to your bones.
Ligaments are bands of tissue that help hold bones, joints and organs in place.
E. Circulatory system
carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
main parts
1. heart serves as pumping organ to push blood in order to flow within the closed system of vessels.
2. blood vessels
serve as passage of blood
3. blood transports oxygen, nutrients, minerals, hormones and waste materials.
F. Nervous system
it serves as the command center since it controls all processes in the body
