General Anatomy & Physiology Flashcards
What is the study of anatomy?
The study of shape and structures of the human body. naming the body parts. systems,directions and body planes and cavities.
what is physiology?
he study of functions and how all parts work together.
The skeletal system
- 206 bone
- function are protection, support , storage minerals , and shape
Skeleton is divided into
axial: skull, spinal cords,
appendicular: upper extermitites and lower
What are the two kinds of bone
Compact bone: it is hard, dense and strong
cancellous bone: spongy bone it is lighter in weight
Bone marrow
- red marrow: filled with blood vessel, red marrow makes red and white blood cells. found in children.
- yellow marrow: contains mainly fat cells it found in adults long bones.
types of joint
fibrous joints: like skull do not move
cartilaginous joints: made of connective tissue and cartilage
synovial joints: these moveable joints
skrletal system disorders?
- osteoporosis: low bone mass
- Arthritis: التهاب المفاصل
-fracture: broken bone
muscular system?
gives the ability to walk, run and digest food and pump blood.
muscular system consists of muscle tissue, connective tissue, nerve issues and blood tissue.
type of muscle tissue
-skeletal or striated: dark and light bond and it is known as voluntary muscle.
- smooth muscle: moves the internal organs
- cardiac muscle
muscle movement
- contraction: become shorter and thicker
- Relaxation:when the muscle return to it original from or shape
muscle
origin: attached to portion that is attached to less movable bone during contraction
Insertion: attached to moveable end of bone
the cardiovascular system
made up of circulatrotu system (arteries veins), heart, lymphatic system.
circulatory system
system transports o2 and nutrients to cells and pick up co2 wastes from the body.
The heart
double walled membranous sac know as pericardium
heats is hollow muscle with 4 chambers
the vessels are named for thire location
- arteries : carry blood away from heart.
-capillaries: vessels that connect the arterial. are so tiny red blood must travel as a line up.
-veins: carry deoxgental toward heart low pressure collecting system to return the waste-filled blood to heart
blood
plasm 91% water.
types of blood cell are
red bloodz: contain protein homoglobin part of oxygen transport.
while blood: leukocytes blood cells function of fighting disease in body.
