Integumentary, Cardiovascular, Lymphatic & Immune System
Question | Answer |
---|---|
According to our text, this is the most neglected of our senses, even though it is the most important. A complete loss of this sense can cause psychotic Breakdown. What sense is it? | Touch |
What are the parts that make up the Integumentary System? | Skin and it's appendages: hair, sebaceous glands, sweat glands, nails and breasts. |
The outer layer of the skin that contains no nerves or blood vessels and consists of sublayers called strata. Contains keratin and melanin. | Epidermis |
The inner layer of the skin composed of dense connective tissue that contains collagen and elastin fibers. | Dermis |
The later of skin found below the dermis that consists of loose connective tissue and fat (adipose) tissue. AKA the "Superficial Fascia" | Subcutaneous layer |
Resistance to disease. | Immunity |
Safety measures established by the Centers for Disease control and Prevention. | Standard Precautions |
A clear, interstitial fluid that bathes the cells and contains lymphocytes which provide immune response; returns plasma proteins that have leaked out through capillary walls; and transports fats from the GI system to the bloodstream | Lymph |
AKA "neoplasm" which is a growth of new tissue that may be benign or malignant. | Tumor |
An acute or chronic skin inflammation characterized by redness, eruptions, edema, scaling and itching | Dermatitis |
What parts make up the Cardiovascular System? There are 3. | Heart, Blood Vessels & Blood |
The pump that sends the oxygen and nutrient rich blood out to the body via the arteries and arterioles. | Heart |
The smallest arteries | Arterioles |
A thick, red fluid that provides oxygen, nourishment, and protection to the cells and carries away waste products. | Blood |
The smallest veins | Venules |
Blood vessels that collect blood from the capillaries and transport it back to the heart. | Veins |
The sack that surrounds the heart and secretes lubricating fluid that prevents friction resulting from movement of the heart | Pericardium |
The actual heart muscle that makes up the thickest part of the heart and generates the contractions. | Myocardium |
The outer membrane of the heart | Epicardium |
The smooth, inner lining of the heart | Endocardium |
The two small, thin walled upper chambers of the heart; the right and left are separated by a thin interatrial septum. | Atriums |
The two large, lower chambers of the heart; they are thick-walled and are separated by a thick interventricular septum. | Ventricles |
A blood vessel that transports oxygenated blood from the heart to the body or deoxygenated blood from the heart to the lungs. | Artery |
One of the three great blood vessels of the heart. It's the artery that carries oxygen and nutrients away from the heart to the body. | Aorta |
One of the three great blood vessels, it's the artery that carries blood to the lungs to release carbon dioxide and take in oxygen. | Pumonary Trunk |
One of the three great blood vessels of the heart, it's the vein that returns poorly oxygenated blood to the right atrium from the upper venous circulation. | Superior Vena Cava |
A major blood vessel: A vein that returns oxygen poor blood from the lower venous circulation to the right atrium. | Inferior Vena Cava |
A major blood vessel: Four veins that take oxygen-rich blood to the left atrium. | Pulmonary Vein |
Arteries that supply oxygenated blood to the heart muscle. | Coronary Arteries. |
The amount of pressure exerted by the blood on the walls of the blood vessels. | Blood Pressure |
The maximal pressure that occurs when the ventricles contract. | Systolic Pressure |
Pressure that occurs when the muscles relax | Diastolic Pressure |
The stages of blood cell development in red marrow constitute a process called what??? | Hematopoiesis |
Red blood cells are also known as what? | Erythrocytes or red blood corpuscles |
An iron-protein compound contained in Red Blood Cells | Hemoglobin |
Serum proteins of the immunoglobulin class that are secreted by plasma cells. | Antibodies |
A straw colored liquid found in blood and lymph and is about 90% water and the rest is made up of nutrients,gases and waste | Plasma |
"Hardening of the arteries" or arteries that have become brittle and have lost their elasticity. | Atherosclerosis |
Passage of blood outside the cardiovascular system. | Hemorrhage |
Small rounded structures located along lymph vessels and are mostly found clustered at the joints. | Lymph Nodes |
In what two ways can specific immunity be acquired? | 1. Natural immunity: The result of exposure. 2. Artificial immunity: In which a substance such as a vaccine is introduced into the body to stimulate the immune response. |
The type of immunity response that involves particular responses to each foreign substance identified. | Specific Immunity |
An immune response which is programmed genetically in the human body. | Nonspecific Response |
Any substance that causes the body to produce antibodies | Antigen |
What are the five main groups of pathogens? | Viruses, Bacteria, Fungi, Protozoa, Pathogenic Animals |
The cells of specific immunity that can recognize and destroy specific molecules. | Lymphocytes |
Lymphocytes develop in the following three ways.... | T Cells - begin in the bone marrow and grow in the thymus. B Cells - grow and develop in the bone marrow Natural killer cells - develop in bone marrow. |
