Integumentary
This is the largest organ of the human body, making up about 16% of total body weight
What is the skin?
Dome shaped muscle which is the primary muscle of inspiration, contracting to increase thoracic volume
What is the Diaphragm?
This vein returns deoxygenated blood from the Upper Body regions to the Right Atrium.
What is the Superior Vena Cava?
This is known as the pacemaker of the heart, responsible for generating the heartbeat
Movement, posture, heat production, joint function, and circulation support
What are key functions of the muscular system?
Mature bone cell responsible for maintaining bone structure
What are Osteocytes?
The Epidermis is primarily made up of these cells.
What are Stratified Squamous Epithelial Cells?
"Voice Box" that houses vocal cords and is located between the Pharynx and the Trachea
What is the Larynx?
These bring oxygenated blood back into the Left Atrium from the lungs
What are Pulmonary Veins?
This is the active phase of the cardiac cycle
What is Systole?
Nerve cell that stimulates muscle fibers
What is a Motor Neuron?
Immovable joints i.e. Bones of the skull
What is Synarthrosis?
This pigment is produced by melanocytes and determines your skin color and provides UV protection
What is Melanin?
Exchange of gases between the blood and tissues of the body
What is Internal Respiration?
These are designed to prevent back flow of blood and ensure that blood will continue flowing forward.
What are valves?
This is associated with the "Lub-Dub" Heart sounds
What is Valve Closure?
This is the site of calcium storage
What is the Sarcoplasmic Reticulum?
What is the Epiphyseal Plate?
What are Stratified Squamous Epithelial Cells?
This is formed from CO2 in the plasma, as well as, a H+ Ion
What is Bicarbonate?
This artery feeds into the heart itself, supplying O2 and nutrients, and removing waste.
What is the Coronary Artery?
Fight or Flight reflex
Main muscle that performs a given function
What is the Prime Mover?
This tough connective tissue membrane covers the outer surface of bones (except at the joints) and serves as an attachment point for tendons and ligaments
What is the Periosteum?
This type of sweat glands become active at puberty and are primarily responsible for body odor due to bacterial action on its secretion.
What are Appocrine Sweat Glands?
What are Dyspnea, Tachypnea, and Bradypnea?
These are the different parts of the Aorta **
What is the Ascending Aorta --> Aortic Arch --> Descending Aorta
**Thoracic Aorta & Abdominal Aorta
This is the reason the AV node delays the signal
What is to maximize Atrial emptying?
This is how calcium affects muscular movements
What is calcium = contraction, absence of calcium = relaxation
What is Calcitonin?
These tiny muscles attached to hair follicles cause "goosebumps" when they contract
What are Arrector Pili Muscles?
This thin, double-layered serous membrane lines the thoracic cavity and covers the lungs, it also maintains negative pressure essential for lung inflation
What is the Pleura?
This circulation carries oxygenated blood from the heart to the body’s tissues and returns deoxygenated blood back to the heart
The amount of blood ejected by one ventricle of the heart during a single contraction
What is Stroke Volume?
Vertebral region that allows for the most rotation
What is the Cervical region?
The portion of the skeleton that includes skull, vertebral, and thoracic cage
What is the Axial Sketelon?
This type of injury can destroy the epidermis, dermis, or hypodermis and can result in loss of sensation due to nerve ending destruction, fluid and electrolyte imbalances, and an increased risk of infection.
What is a Burn?
Respiratory membrane is covered in this ensuring that the alveoli remain patent
What is Surfactant?
This is the flow of blood through the heart, including all valves, veins, arteries, and chambers of the heart.
What is Superior/Inferior Vena Cava --> R. Atrium --> Tricuspid Valve --> R. Ventricle --> Pulmonary Valve --> Pulmonary Arteries --> Lungs --> Pulmonary Veins --> L. Atrium --> Mitral (Bicuspid) Valve --> L. Ventricle --> Aortic Valve --> Aorta --> Body
Created by vasometer mechanisms that reflect changes in vessel diameter, smooth muscle relaxation vs contraction.
What is Peripheral Resistance?
This diseases characterized by decreased bone mass and increased fracture risk
