Heart Chambers

By: Administrator, Views: 10748

Circulation of blood through the chambers of the heart Septum divides heart into the right and left heart. Each side contains an upper and lower chamber: Atria, or upper chambers, receive blood. Ventricles, or lower chambers, pump blood. Valves control intake and outflow of blood in chamber...

Exercise and cardiac output & Definition of stroke volume

By: HWC, Views: 7674

▪ Cardiac output: • Maintains blood flow throughout the body. • Measure of blood volume ejected from the heart over a given time. • Determined by multiplying heart rate by stroke volume (CO = SV x HR). • Heart rate: Number of beats/min. • Stroke volume: Amount of blood eject...

Electrocardiogram Examination

By: Administrator, Views: 10567

An electrocardiogram (ECG or EKG) is a test that checks how your heart is functioning by measuring the electrical activity of the heart. With each heartbeat, an electrical impulse (or wave) travels through your heart. This wave causes the muscle to squeeze and pump blood from the heart. Sinoat...

Role of the respiratory system - effect of altered ventilation rates

By: HWC, Views: 7582

• Dissociation of the chemical substances in the body fluids can result in the production of free hydrogen ions. • The pH scale is used to measure the concentration of hydrogen ions in solution. • Normal blood pH values vary around 7.4. • When hydrogen ion concentration increases, t...

TRH/TSH/Thyroid hormone

By: HWC, Views: 7250

Thyroid hormone production • A decline in metabolic rate caused by increased metabolic need or physical exertion stimulates the production of thyrotropin hormone releasing (TRH) hormone from the cells of the hypothalamus. • Thyrotropin hormone releasing hormone targets the thyrotrophic ce...

Abnormal Heart Sounds

By: Administrator, Views: 761

An electrocardiogram (ECG, EKG) is a commonly used procedure in which the electrical events associated with the beating of the heart are evaluated. (A) Skin electrodes are applied to the chest wall, which send electrical signals to a computer that interprets the signals into graph form. An ele...

Factors that increase metabolic rate and heat production

By: HWC, Views: 7755

• All vital biochemical reactions are temperature dependent. • The overall rate at which metabolic reactions use energy is known as the metabolic rate. • Metabolic rate greatly determines body temperatures. • Temperature is maintained by balancing the loss of heat to the environment...
