National 5 Biology - Transport in Animals

Identify the atria.

identify the right ventricle

identify the pulmonary artery

identify the vena cava

identify the chambers where blood leaves from

Organise these features into the right blood vessels

Groups:

(a) Veins

,

(b) Arteries

,

(c) Capillaries

• thick muscular walls

• Carries blood into the heart

• location of gas exchange

• carries blood away from the heart

• thin muscular walls

• one cell thick

• wide channel for blood to flow

• narrow channel for blood to flow

Match the correct features of blood cells to the correct cell type

• Produce antibodies to fight pathogens

• Lymphocytes

• Engulf pathogens

• Phagocytes

• Transport oxygen around the body

• Red blood cells

Microbes that cause disease are known as being

At the lungs​ (a)   becomes​ (b)   due to gas exchange.

• haemoglobin
• oxyhaemoglobin
• deoxygenated
• oxygenated

Reorder the stages of events involved in phagocytosis.

• Phagocyte detects a pathogen.

• Phagocyte releases the waste products.

• Phagocyte engulfs the pathogen.

• Phagocyte approaches a pathogen.

• Phagocyte digests the pathogen.
