Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Blood is more than a red liquid.
Blood is a connective tissue with a fluid matrix called plasma and formed elements: RBCs, WBCs, and platelets. Plasma carries nutrients, wastes, and hormones.
↳ Blood = plasma + cells, a transport system for nutrients, wastes, and hormones.
Gases dissolve in plasma too.
Plasma carries small amounts of oxygen and carbon dioxide in dissolved form. Most oxygen is in RBCs, but about 1.5% is dissolved in plasma. About 5-7% of CO₂ is dissolved, mostly as bicarbonate ions.
↳ Plasma carries ~1.5% O₂ and 5-7% CO₂, mostly as bicarbonate.
Biconcave oxygen carriers.
RBCs are biconcave, disc-shaped cells with a central depression. They contain haemoglobin, which binds oxygen and gives blood its red color. They transport oxygen and a little CO₂.
↳ RBCs are biconcave cells packed with haemoglobin for gas transport.

16 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which of the following is NOT a component of plasma?
BeginnerHaemoglobin
Plasma carries nutrients like glucose and amino acids, hormones, and wastes, but haemoglobin is contained in red blood cells, not in plasma.
Approximately what percentage of oxygen is transported dissolved in plasma?
Intermediate1.5%
About 1.5% of oxygen is dissolved in plasma; the majority is carried by haemoglobin in RBCs.
Which blood cells are biconcave and contain haemoglobin?
BeginnerErythrocytes
Red blood cells (erythrocytes) are described as disc-shaped (biconcave) and contain haemoglobin.
In adults, red blood cells are formed in the:
IntermediateRed bone marrow of short bones
Before and immediately after birth, RBCs are formed in liver and spleen, but in adults they are formed in the red bone marrow of short bones like sternum, ribs, and vertebrae.
