Human Anatomy Flashcard

Front

Three vessels that carry blood:

Back

Arteries, Veins, Capillaries

Answer explanation

The three vessels that carry blood around the body are arteries, veins, and capillaries. Arteries transport oxygenated blood away from the heart, veins carry deoxygenated blood back, and capillaries facilitate exchange between blood and tissues.

Front

Colour of lymphatic fluid?

Back

Straw-coloured

Answer explanation

Lymphatic fluid, also known as lymph, is typically straw-coloured due to its composition, which includes water, proteins, and white blood cells. This distinguishes it from other bodily fluids like blood, which is red.

Front

Vein that connects lymph and blood:

Back

Subclavian vein

Answer explanation

The subclavian vein is the vessel that connects the lymphatic system to the bloodstream, allowing lymph to re-enter circulation. It is located beneath the clavicle and plays a crucial role in this process.

Front

Bones of the forearm:

Back

Radius and Ulna

Answer explanation

The forearm is made up of two bones: the radius and the ulna. The humerus is the upper arm bone, the femur is in the thigh, the tibia and fibula are in the lower leg, and the scapula and clavicle are part of the shoulder girdle.

Front

Foot arches:

Back

Three: Medial, Lateral, Transverse

Answer explanation

The foot has three main arches: the Medial arch, which runs along the inside; the Lateral arch, which runs along the outside; and the Transverse arch, which runs across the foot. This structure supports weight and provides balance.

Front

Stoutest bone in the body

Back

Tibia (lower leg)

Answer explanation

The stoutest bone in the body is the tibia, which supports weight and withstands stress in the lower leg. While the femur is the longest bone, the tibia is denser and stronger, making it the stoutest.

Front

Another name for the calf muscle

Back

Gastrocnemius

Answer explanation

The calf muscle is primarily made up of the gastrocnemius, which is responsible for plantar flexion of the foot. The other options refer to different muscle groups: biceps (arm), quadriceps (thigh), and deltoid (shoulder).

Front

Blood vessel carrying oxygenated blood from heart to extremities.

Back

Arteries

Answer explanation

Arteries are the blood vessels responsible for carrying oxygenated blood away from the heart to the body's extremities, making them the correct choice for this question.

Front

Primary function of red blood cells

Back

Carry oxygen

Answer explanation

The primary function of red blood cells is to carry oxygen from the lungs to the body's tissues and return carbon dioxide to be exhaled. This is essential for cellular respiration and overall metabolic processes.

Front

Bone known as collarbone?

Back

Clavicle

Answer explanation

The clavicle is commonly known as the collarbone. It connects the arm to the body and is located above the first rib, making it easily identifiable.
