The Circulatory? Vascular System
What are the two interrelated subsystems called in the circulatory system?
1. The cardiovascular or blood-vascular system
2. The Lymph-vascular system or lymphatic system
The average resting heart rate is?
60 to 100
Erythrocytes or Red Corpuscles
What are tubular, elastic, thick-walled, branching vessels? Carry blood from the heart through the body.
Arteries
Split into the internal and external carotid arteries; Supplies blood to the head, face, and neck
Common Carotid Artery (CCA)
What controls the circulation of blood and lymph throughout the body?
The Circulatory System/ Vascular System
What contracts and relaxes to force blood to move through the circulatory system?
The Pericardium
What attracts oxygen molecules through a process known as oxygenation?
Hemoglobin
What are tubular, elastic, thin walled, branching vessels that carry impure blood from the capillaries to the heart.
Veins
Breaks into smaller branches and supplies blood to lower portion of the face, including the mouth and nose.
External Maxillary aka Facial Artery
What is responsible for the circulation of blood to include the heart, arteries, veins, and capillaries
The Cardiovascular System
The interior of the heart contains four chambers. Name them.
1. Right Atrium
2. Left Atrium
3. Right Ventricle
4. Left Ventricle
Fights bacteria and other foreign substances and increases in number when infection invades the body.
White Blood cells (WBCs) are also called leukocytes
These are small vessels that take nutrients and oxygen from the arteries to the cells. Take waste products from the cells to the veins.
Capillaries
supplies blood to the knee joint and muscles in the thigh and calf
Popliteal
Responsible for the circulation of lymph to include nodes (gland-like structures) and lymphatic vessels
The Lymph-vascular or Lymphatic system
What is the function of the blood?
1. Transport oxygen, waste, nutrients, and hormones
2. Protect the body from the threat of infection and disease-causing bacteria, and by using platelets that cause clotting of the blood, limit loss of blood.
3. Regulate the temperature, PH balance, and blood pressure of the body
What is responsible for clotting blood?
Blood Platelets or Thrombocytes
Oxygen-poor blood enters the right atrium of the heart through the?
Superior vena cava and inferior vena cava
Supplies blood to the little finger side of the forearm and the smaller arteries in the hand
Ulnar
How many seconds does it take the red blood cells to circle the whole body?
20 seconds
These words are used to describe the blood.
Sticky, salty fluid
What % of the blood is made up of Plasma and what % water?
55% Plasma and 90% Water
Blood travels through the pulmonary artery to the lungs, where it is oxygenated. This phase of the circulation of blood is referred to.
Pulmonary circulation
Is the second subsystem of the circulatory system and is responsible for picking up and returning leaked tissue fluid and plasma proteins to the cardiovascular system
Lymph-vascular system, also known as the lymphatic system
