Study Notes
Blood and Circulation
- Blood direction in veins is regulated by valves, preventing backflow.
- Plasma is the liquid component of blood, making up the majority.
- Erythrocytes (red blood cells) are responsible for oxygen transportation.
Anatomy of the Throat and Lungs
- The thyroid cartilage is commonly known as the Adam's apple.
- During exhalation, the diaphragm relaxes.
- The rib cage is formed by the sternum and ribs; it protects thoracic organs.
Musculoskeletal Connections
- Humerus and ulna form the elbow joint.
- The patella, also known as the kneecap, is vital for knee function.
- Muscle origins are stationary points during contraction; the quadriceps have four origins.
Nervous System Overview
- The cerebral cortex manages higher brain functions.
- There are 12 thoracic spinal nerves in the human body.
- Central nervous system (CNS) comprises the brain and spinal cord.
Digestion and Metabolism
- Most nutrient absorption occurs in the jejunum region of the small intestine.
- Digestion begins in the mouth, where food is mechanically broken down.
- The large intestine's main role is to absorb water from indigestible food.
Endocrine Functions
- Hematopoiesis occurs in red bone marrow, producing blood cells.
- Testes are male reproductive organs, responsible for sperm production.
- The hypothalamus indirectly controls growth by influencing the pituitary gland.
Heart and Respiratory System
- Blood pressure readings consist of systolic and diastolic pressures.
- The left ventricle pumps oxygenated blood into the aorta.
- A healthy heart pumps approximately 5 liters of blood per minute during rest.
Muscle and Bone Structures
- Cardiac muscle is involuntary, keeping the heart beating unconsciously.
- Bones protect vital organs and support body structure; adults have 206 bones.
- Myofibrils are responsible for muscle contractions, found in skeletal muscle.
Female Reproductive System
- Fertilization typically takes place in the fallopian tubes.
- The placenta releases hormones and provides nutrients to the fetus.
Respiratory Pathways
- The primary entryway for breathing is the nose.
- The left lung is composed of two lobes, allowing efficient gas exchange.
Special Functions
- Cerebrospinal fluid circulates in the ventricles and subarachnoid space, providing cushioning.
- Platelets are responsible for blood clotting, essential for wound healing.
Senses and Integration
- Motor neurons signal muscle contraction, playing a crucial role in movement.
- Integration of sensory data primarily happens in the central nervous system.
Glandular Functions and Disorders
- Parathyroid glands manage calcium levels, influencing conditions like kidney stones.
- The adrenal glands play a role in stress responses through hormone release.
Digestive Pathway
- Food travels through the esophagus, stomach, and intestines; the liver does not participate in this process directly.
