Anatomy and Physiology: Practical Midterm Review

Cardiac tissue consists of striated muscle cells connected by intercalated discs, enabling coordinated contractions.

Capillaries are small blood vessels that facilitate the exchange of oxygen, carbon dioxide, and nutrients between blood and surrounding tissues.

Stratified squamous epithelium is a type of tissue composed of multiple layers of cells, where the outermost layer is made up of flattened (squamous) cells.

A red blood cell (erythrocyte) is a type of blood cell that contains hemoglobin and transports oxygen throughout the body.

A follicle is a small, spherical structure in the body that contains cells. Follicles are found in thyroid glands and ovaries.

A normal blood smear is a blood sample that is spread onto a glass slide and stained to allow microscopic examination of the blood cells.

A Korotkoff sound is a sound heard during the taking of blood pressure using a sphygmomanometer and stethoscope, that represents the turbulent flow of blood through an artery as pressure is released.

The R wave represents ventricular depolarization and is a positive deflection.

The hilus is a depression or fissure where structures such as blood vessels or nerves enter an organ.

Atrial contraction follows after the P wave, the indentation indicates the start of the QRS complex.
