The vegetable that shares its name with a human body part is "artichoke." While it is primarily known as a vegetable, the term "choke" in "artichoke" refers to a part of the plant rather than a human body part, but it is often humorously associated with the act of choking. However, another example is "beet," which can refer to "beetroot" and sounds similar to "beat," as in a heartbeat, but it doesn't directly name a body part. Overall, vegetables like "chickpeas" may also loosely fit the criteria through playful language, but the connection can be more abstract.
