exchange between oxygen and carbon dioxide which takes place in alveoli is called as

• external respiration

• internal respiration

• cellular respiration

exchange between oxygen and carbon dioxide near with body tissue is called as

• external respiration

• internal respiration

• cellular respiration

choose all correct statements about external respiration!

• the process involving role of alveoli

• O2 concentration in alveoli is higher than in RBC so O2 move to RBC

• CO2 concentration in RBC is higher than in alveoli so CO2 move to alveoli

• the gas exchange happen by passive transport

• from alveoli, RBC rich with O2 are sent to heart, and received by left atrium

choose all correct statements about external respiration!

• RBC rich of CO2 is coming from heart, transported by pulmonary artery, and later the CO2 diffuse to alveolar space

• external respiration involves air in external environment

• the gas exchange happen by active transport

• from alveoli, RBC rich with O2 are sent to heart, and received by left atrium

these are the characteristics of alveoli which allow diffusion of gases happen efficiently. choose all that apply!

• they have thin wall only consists of a single layer of cell

• they are always moist

• they are surrounded with web-like capillaries

• their size is so small, giving an increase of total surface area

which one of this showing a combination between haemoglobin with the gas they bring while the RBC is oxygenated?

• oxyhaemoglobin

• carbaminohaemoglobin

• carboxyhaemoglobin

• haemoglobinic acid
