Study Notes

Red Bone Marrow and Lymphatic System

Red bone marrow produces blood cells and is crucial for immune function.
Thymus plays a vital role in the maturation of T lymphocytes, essential for adaptive immunity.
Lymphatic vessels transport lymph, a fluid containing white blood cells, returning it to the bloodstream.
Spleen filters blood, removing old red blood cells and storing lymphocytes.
Lymph nodes act as filters for harmful substances and contain immune cells that can help fight infection.

Hormonal Glands and Metabolic Regulation

Hormonal glands include the thyroid, pituitary, adrenal glands, pancreas, pineal gland, ovaries, and testes.
These glands secrete hormones that regulate growth, reproduction, and metabolism (nutrient usage).

Respiratory System

Functions to keep blood supplied with oxygen and remove carbon dioxide.
Gaseous exchanges occur in the alveoli, the air sacs of the lungs.
Structure includes the nasal cavity, pharynx, larynx, trachea, lungs, and bronchus.

Cardiovascular System

Blood vessels transport blood, carrying oxygen, nutrients, and waste products throughout the body.
The heart pumps blood to maintain circulation.

Digestive System

Breaks down food into absorbable nutrients that enter the bloodstream.
Indigestible food is eliminated as feces.
Key components: oral cavity, esophagus, liver, stomach, small intestine, large intestine, rectum, anus.

Urinary System

Eliminates nitrogenous wastes and regulates body fluids, electrolytes, and acid-base balance.
Main organs include kidneys, ureters, urethra, and urinary bladder.

Male Reproductive System

Primary function is the production of offspring.
Testes produce sperm and male sex hormones, while ducts and glands assist in delivering sperm.
Key structures: prostate gland, penis, testes, scrotum, vas deferens.

Female Reproductive System

Ovaries produce eggs and female hormones. Other structures facilitate fertilization and fetal development.
Mammary glands produce milk for nourishing newborns.
Key components: ovaries, uterus, vagina, fallopian tubes.

Anatomical Regions

Umbilical Region: central area surrounding the navel.
Epigastric Region: located above the umbilical region.
Hypogastric (Pubic) Region: found below the umbilical region.
Iliac or Inguinal Regions: located lateral to the hypogastric region, near hip bones.
Lumbar Regions: lateral to the umbilical region, aligns with the lower back.
Hypochondriac Regions: found below ribs, lateral to the epigastric region.

Molecular Biology and Cellular Structure

Essential elements for life include Hydrogen (H), Oxygen (O), Nitrogen (N), Phosphorus (P), Calcium (Ca), and Sulfur (S).
Molecules consist of two or more atoms, forming essential compounds like DNA and glucose (blood sugar).

Levels of Biological Organization

Cellular Level: Cells are the fundamental unit of life, e.g., muscle and nerve cells.
Tissue Level: Tissues are groups of similar cells performing common functions.
Four Basic Tissue Types:
- Epithelial: Covers body surfaces and lines cavities.
- Connective: Supports and protects organs.
- Muscular: Provides movement.

Ventral Cavity and Membranes

Thoracic Cavity: subdivided into pleural cavities (holding lungs) and pericardial cavity (holding heart).
Abdominopelvic Cavity: divided into abdominal cavity (containing digestive organs) and pelvic cavity (containing reproductive and excretory organs).
Serous Membranes: cover walls and organs of the ventral body cavity to prevent friction.
- Parietal Serosa: lines cavity walls.
- Visceral Serosa: covers organs within the cavity.
- Serous Fluid: lubricates the space between serous membranes.

Description

This quiz covers the functions of the human excretory system, including the roles of kidneys and related organs in waste elimination and fluid balance. It also explores the male reproductive system, focusing on the production of offspring and the functions of the testes and male ducts.
