ANATOMY AND PHYSIOLOGY OF HUMAN HEART The human heart is a cone shape‚ hollow‚ muscular organ located in the mediastinum between the lungs. It is a about the size of an adult fist. The heart rests on the diaphragm‚ tilting forward and to the left in the client’s chest. Each beat of the heart pumps about 60ml of blood‚ or 5L/min. During strenuous physical activity‚ the heart can double the amount of blood pumped to meet the increased oxygen needs of the peripheral tissues. ANTERIOR VIEW

Tissues in the Body Unit 5 – Anatomy and Physiology for Health and Social Care Epithelial Cuboidal – cube shaped‚ prominent nucleus. Can be found in medulla of kidney. Does not allow for passive diffusion easily. Columnar – tall‚ vertical‚ thick cells. Can be found in the small intestine. Does not allow passive diffusion easily. Active transport is needed. Move nutrients from intestine to blood = absorption! Can have microvilli to increase surface area. Squamous – large‚ thin and prominent

9.01 Brings oxygenated air to the alveoli. Removes air containing carbon dioxide. Filters‚ warms‚ and humidifies the air. Produces sound (speech). Helps with sense of smell. Assists to regulate the pH within the blood. 9.02 Nose- Nares/Nostrils- Allow entrance for air. Nasal Cavity- Lined with mucous & ciliated epithelium. Air is filtered‚ warmed‚ and humidified. Nasopharynx- Part of the throat serving only as a passageway for air. Pharynx- Throat. 3 Passageways that serve for air

Determining the Latent Period 1. Click Clear Tracings to erase the oscilloscope display. The voltage should be set to 5.0 volts. 2. Drag the 200 msec button to the right edge of the oscilloscope. 3. Click the Stimulate button once‚ and allow the tracing to complete. 4. When you measure the length of the latent period from a printed graph‚ you measure the time between the application of the stimulus and the beginning of the first observable response(increase in force). The computer can’t “look ahead
