Skeletal
Bone-building cells
What are osteoblasts?
Is both an involuntary muscle and has intercalated discs
What is the cardiac muscle?
Transportation (nutrients, hormones, waster, and heat), regulation (maintains homeostasis of all body fluids), and protection (blood clotting, white blood cells, antibodies, interferon and complement)
What is one main function of the blood?
Prevents backflow of blood
What is the function of the heart valve?
This type of blood vessel carries oxygen-rich blood away from the heart.
What is an artery?
The longest bone in the body
What is the femur?
Site where muscle is attached to the movable bone and move during contraction
What is the insertion?
A clot that breaks away from the vessel wall and floats freely in the bloodstream
What is an embolus?
The pacemaker of the heart that releases electrical stimuli (upper part of heart’s right atrium)
What is the Sino-atrial (SA) node?
This circuit carries blood from the left side of the heart to all the other organs of the body and back to the left side of the heart; sends oxygenated and nutrient-rich blood out to cells and returns deoxygenated blood to the heart
What is systemic circulation?
Cylindrical end of one bone that fits into a trough-shaped surface on another bone (elbow and ankle joint)
What is a hinge joint?
The chemical needed to transmit a nerve impulse to a muscle
What is acetylcholine?
The three formed elements
What are erythrocytes, leukocytes, and platelets?
This structural part of the heart is one cell layer thick, exchange gases and nutrients, and a terminal arteriole branches into 10 to 20 of these
What are capillaries?
The main artery that carries oxygen-rich blood from the heart to the body is called this.
What is the aorta?
Broken bone ends are forced into each other. Commonly occurs when someone attempts to break a fall with outstretched arms
What is an impacted bone fracture and how does it typically happen?
Type of muscle contraction where myofilaments are successful in sliding movements, muscle shortens, and movement occurs
What are isotonic contractions?
The stoppage of bleeding: Vascular Spasms, Platelet Plug Formation, Coagulation/Blood Clotting
What is hemostasis and its three stages?
Transports deoxygenated blood from the right side of the heart to the lungs to absorb oxygen and release carbon dioxide, oxygenated blood then flows back to the right side of the heart
What is the pulmonary circulation?
This type of high blood pressure can lead to an increased risk of heart disease and stroke.
What is hypertension?
The bone breaks bone matrix/deposits salts in response to changes in calcium ion level in the blood and pull of gravity and muscles on the skeleton
What is bone remodeling?
The synapse between a motor neuron and a muscle fiber, where nerve impulses trigger muscle contraction
What is a neuromuscular junction?
When typing a patient's blood, agglutination occurred with anti-A and anti-Rh antibodies. What is this patient's blood type?
What is A positive (A+)?
The part of the heart’s intrinsic conduction system that carries impulses into the interventricular septum
What is the Atrioventricular (AV) bundle?
The series of events that occur during one complete heartbeat, from the beginning of ventricular contraction to the start of the next contraction
What is the cardiac cycle?
