| Question | Answer |
|---|---|
| Describe the circulatory system. | Includes the heart and blood vessels, transporting blood, oxygen, and nutrients. |
| List the organs in the circulatory system and their functions. | Heart: Pumps blood throughout the body. Blood Vessels (arteries, veins, capillaries): Transport blood. |
| Describe the respiratory system. | Composed of the lungs and airways, facilitating oxygen intake and carbon dioxide removal. |
| List the organs in the respiratory system and their functions. | Lungs: Facilitate oxygen intake and carbon dioxide removal. Trachea: Connects the throat to the lungs. Bronchi: Passageways for air into the lungs. |
| Describe the digestive system. | Includes the stomach, intestines, liver, and other organs that break down and absorb nutrients. |
| List the organs in the digestive system and their functions. | Stomach: Breaks down food S. Intestine: Absorbs nutrients L. Intestine: Absorbs water and forms feces Liver: Detoxify chemicals and metabolizes drugs Pancreas: Produce digestive enzyme and hormone ex. insulin Gallbladder: Store bile for fat digestion |
| Describe the nervous system. | Composed of the brain, spinal cord, and nerves, controlling body functions and responses. |
| List the organs in the nervous system and their functions. | Brain: Controls body functions and processes. Spinal Cord: Transmits signals between the brain and body. |
| Describe the muscular system. | Encompasses all muscles, enabling movement and maintaining posture. |
| Describe the skeletal system. | Consists of bones and joints, providing structure and support. |
| List the organs in the skeletal system and their functions. | Bones (206 total): Provide structure and support. Bone Marrow: Produces blood cells. |
| Describe the endocrine system. | Includes glands that release hormones for regulation of processes like growth and metabolism. |
| List the organs in the endocrine system and their functions | Pituitary Gland: Regulate growth Pineal Gland: Makes melatonin Thyroid Gland: Control metabolism Parathyroid Gland: Regulates calcium level Adrenal Gland: Makes hormones like adrenaline Pancreas: Regulate blood sugar Ovary/Testes: Makes sex hormones |
| Describe the reproductive system. | Involves organs like the ovaries and testes, facilitating reproduction. |
| List the organs in the reproductive system and their functions. | Ovaries: Produce eggs and hormones. Testes: Produce sperm and testosterone. Uterus: Supports fetal development. Prostate Gland: Produces seminal fluid. |
| Describe the excretory system. | Composed of the kidneys and bladder, removing waste from the body. |
| List the organs in the excretory system and their functions. | Kidneys: Filter blood to produce urine. Ureters: Transport urine from kidneys to bladder. Bladder: Stores urine. Urethra: Removes urine from the body. |
| Describe the immune/lymphatic system. | Includes the lymph nodes and spleen, defending against pathogens. |
| List the organs in the immune/lymphatic system and their functions. | Spleen: Filters blood and supports immunity. Lymph Nodes: Filter lymph and produce white blood cells. Thymus: Matures T-cells for the immune system. |
| Describe the integumentary system. | Includes the skin, hair, and nails, protecting the body and regulating temperature. |
| List the organs in the integumentary system and their functions. | Skin: Protects the body and regulates temperature. Hair: Insulates and protects skin. Nails: Protect the tips of fingers and toes. |
| Describe the flow of blood through the heart. | Oxygen-poor blood enters the right atrium from the body, then moves to the right ventricle, which pumps it to the lungs → Oxygen-rich blood returns to the left atrium, flows into the left ventricle, and is then pumped to the body through the aorta |
| Superior (cranial) | Toward the head or upper part of a structure or the body; above. |
| Inferior (caudal): | Away from the head or toward the lower part of a structure or the body; below. |
| Anterior (ventral) | Toward or at the front of the body; in front of. |
| Posterior (dorsal) | Toward or at the back of the body; behind. |
| Medial | Toward or at the midline of the body; on the inner side. |
| Lateral | Away from the midline of the body; on the outer side. |
| Axial | Includes the head, neck, and trunk. |
| Appendicular | Includes the limbs (arms and legs). |
| Sagittal plane | Divides the body vertically into right and left parts. |
| Midsagittal (median) plane | A sagittal plane that lies exactly in the midline. |
| Frontal (coronal) plane | Divides the body vertically into anterior (front) and posterior (back) parts. |
| Transverse (horizontal) plane | Divides the body horizontally into superior (top) and inferior (bottom) parts. |
| Oblique section | A cut made at an angle other than 90° to the vertical plane. |
| Dorsal body cavity | Protects the nervous system |
| Ventral body cavity | Houses internal organs (viscera) |
