Compartmentation: Cells And Tissues Flashcards
What are the basic functional unit of living organisms, and that can carry out all the processes of life?
Cells
What are the three major cavities that the body is anatomically divided into?
Cranial cavity
Thoracic cavity
Abdominopelvic cavity
The cranial cavity contains what?
The cranial cavity contains the brain, our primary control center.
What does the thoracic cavity contain?
The thoracic cavity contains the heart, which is enclosed in a membranous pericardial sac, and the two lungs, enclosed in a separate pleural sac.
The abdomen and pelvis form one continuous cavity, the abdominopelvic cavity, which contains what?
Stomach, intestines, liver, pancreas, gallbladder, and spleen.
What is the tissue that lines the abdomen?
The peritoneum lines the abdomen and surrounds the organs within it.
What organs are not found in the abdominopelvic cavity?
The kidneys lie outside the abdominal cavity, between the peritoneum and the muscles if the back.
What is the location of Simple Squamous Ept?
Lung alveoli, the blood vessel wall, the lining of the heart, the kidney glomeruli, and the corpuscles
What is the Function of Simple Squamous Ept?
Diffusion & filtration
Where is the location of Stratified Squamous Ept?
Esophagus, and the vagina
What is the function of Stratified squamous Ept?
Protection
Where is the location of Simple Cuboidal Ept?
Kidney tubules, ducts of small glands, ovary surface
What is the function of Simple Cuboidal Ept?
Absorption & secretion
Where is the location of Pseudostratified ciliated columnar Ept?
Trachea, Lung bronchus
What is the function of Pseudostratified ciliated columnar?
Secretion and propulsion of mucus up and out of the respiratory tract
Where is the location of Transitional Ept?
Lines the ureters and bladder, and part of the urethra
Where is the location of Loose areolar c.t. ?
Under the epithelial of the body, packages organs, surrounds capillaries, and between the muscles
What is the function of Loose areolar c.t. ?
Wraps and cushions organs and protection
Where is the location of Adipose c.t. ?
The hypodermis, around the kidneys, eyeballs, within the abdomen, in the breasts, and around the heart
What is the function of Adipose c.t. ?
Insulates, supports, protects and provides a reserve source of fuel and energy storage
Where is the location of Hyaline cartilage?
Embryonic skeleton, covers the ends of long bones, forms costal cartilages of the nose, trachea and larynx.
What is the function of Hyaline cartilage?
Supports and reinforces
Where is the location of Bone (Osseous) tissue?
The skeleton
What is the function of Bone (Osseous) tissue?
Support, protection, and mineral storage
Where is the location of the blood?
Within the cardiovascular system
What is the function of blood?
Transport gases, wastes, glucose & hormones etc…
What are the four main classes of connective tissue?
- Connective Tissue Proper
- Cartilage
- Bone Tissue
- Blood
What is the body location of skeletal muscle?
Skeletal muscle is found within the skeletal muscle that is attached to bones
What are the structural features of Skeletal Muscle?
Long cylindrical, multinucleated cells, has striations also referred to as bands.
What is the function of Skeletal Muscle?
It is voluntary movement, locomotion facial expression, support
What is the body location of Cardiac Muscle?
The walls of the heart
What are the structural features of Cardiac Muscle?
Striated, uninucleated cells, that (branch) interdigitate at specialized Jxns called intercalated discs
What is the function of Cardiac Muscle?
When it contracts, it propels blood into and through the cardiovascular system. (Circulation)
Involuntary control
Where is the body location of Smooth Muscle?
Mostly in the walls of hollow organs. Blood vessels, uterus, and urinary organs
What are the structural feature of Smooth Muscle?
Spindle shaped cells with central nuclei.
No Striations
Cells are arranged to form sheets
What is the function of Smooth Muscle?
Propels substances or objects (foodstuff, urine, a baby) along internal passage ways
Involuntary Control
