1) Immune System (It could be weakened from fighting the cold) and the Integumentary System (From being rubbed by a tissue)
2) Skeletal System (You broke a bone, which is part of this system) and the Muscular System (That muscle will have limited mobility from being casted, and will slightly weaken)
3) Respiratory System (With asthma attacks, your lungs work hard to accommodate to your oxygen needs) and the Cardiovascular System (Your heart rate naturally increases during an asthma attack)
4) Integumentary System (Your skin is damaged from the sunburn) and the Immune System (Your immune system might be at risk for being less likely to fight off disease, depending on the severity of the burn)
Hope this helps!
